Credit: NASA/Goddard Space Flight Center Scientific Visualization Studio._Stellar surface fusion occurs above a star's photosphere to a limited extent as found in studies of near coronal cloud activity. _Surface fusion is produced by reactions during or preceding a stellar flare and at much lower levels elsewhere above the photosphere of a star. _"Nuclear interactions of ions accelerated at the surface of flaring stars can produce fresh isotopes in stellar atmospheres."[1] [It references a 2008 paper at arXiv]
